DIRECTORY.

5 To all fao/wm t 'may concern.'

` vision for indexing` the different subjects in such manner that the information can be readily found, even though it should be carried on a page not identified by an index character corresponding with vthe index let ter ofthe subject under investigation.

The accompanying-'drawings illustrate the invention: 1 y i Figure` l is a plan view of edirectory constructed in accordance with the provisions of this invention, the directory being open to the middle pages;

Figure 2 `is a fragmental view of one of the pages of the'directory; and

Figure 3 is a fragmental view of another page of the directory. i

The directory comprises a seriesof leaves l, 2, suitably bound together by fastenings 3. The uppermost leaf lis provided along both side margins with suitable index characters 4. The index characters employed, in this instance, are letters of the alphabet. The leaf l is ruled longitudinally and crosswise with lines 5, 6, respectively, to .forni rectangular spaces, in which spaces may be written the key words or index terms 10 of the subjects on which the information is to be given. For example, in alinement with the index letter G is the Word Garages, and opposite the index letter E are the words Electric wiring.7 Opposite the letter D will be foimd the words Deer and duck hunting. Also opposite the index letter D will be found the word Detective.

Associated with some of the index terms l0 are sub-index characters 7 whose function will be explained hereinafter.

The leaves 2 are severally indexed, and for this purpose each is provided with a tab 8, the tabs of succeeding leaves being overlapped by those of preceding leaves similar Specification of Letters Patent. Patented 3111196, ApplicationnIedNOVember l0, 1920. 'Serial No. 423,093.

tothe well-known thumb indexes of dictionaries and the like. Each 'tab 8 carries a different index character 9, which corresponds with the index character t in alinement therewith oir the leaf l. For.identification pur-` poses the index characters 4, 9, willhereinI after be termed main index characters tto distinguish them from thesub-indexchar-` acters 7 above referred-to.

The leaves 2 bear various. subjects 1l of information. Now referring more particularly to Figure f2, said figure shows a portion of the leaf bearing the index. character G and this leaf accordingly bears 'the names and addresses of individuals or firms operating garages and other business, or any other subject of information, which ordi-` narily would be listed on the leaf having the i index character G. ln compiling the directory, 1t may be found, as in the instance gustV mentioned, that a certain page 1s not entirely. taken upV by the subjects that would ordinarily be carried on such page. In a directory of this class there would, therefore, be a natural tendency to make it more or less bulky relative to `the amount of information contained on the pages, since a large portion of many of the pages would beonly':

partially filled with information. Nowy referring to the leaf l, it maybe noted that in i alinement with the index letter C is Carpet cleaning Gf. The sub-index character UG, just mentioned, indicates that carpet cleaning establishments will be found indexed, not where they would logically be expected to be listed on `the leaf 2 having the index letter C thereon, but on the leaf 2 identifie-d by the main index character G '"r, and, again referring to Figure 2, we find that the carpet cleaning establishments are listed on the leaf 2 bearing the main index character G.

As another example of indexing the subjects, it will be noted that Electric wiring is listed on the leaf l opposite the letter 13, and by referring to Figure 3 it is seen that the electrical contractors are properly listed on the leaf bearing the index character E. The firms which it may be desired to list on the leaf designated by the letter E may only occupy a portion of said leaf, and, consequently, firms which vlogically would be looked for Linder other index letters may be found listed on, the leaf identified by the index, character E In order, however, to

alphabetically indexed or `listed firms, the

VFrom the foregoing, it Will be clear thatv space may be economized so that a relatively large amount ofinforniation can be carried by a directory of small dimensions, and that the main and subfindex characters make it possible to readily refer to the particular page in the directory bearing the desired information. i

I claim:

l. In a directory, the combination of a series of leaves, the uppermost leaf having different marginal index characters and being provided in alinement with said index characters With the corresponding index terms of various subjects of information arranged in successive columns, the other leaves having tabs respectively alined with the index characters and each leaf bearing information corresponding with at least one of the index characters that is alined with its tab.

2. In a directory, the combination of a series of leaves, the uppermost leaf having different marginal index characters and being provided in alinement with said index characters with the corresponding index terms of various subjects of information and having adjacent at least'one of the index terms a sub-index character, the other leaves having tabs respectively alined with the in dex characters and each bearing information corresponding with the index character that is alined With its tab and at least one of said other leaves bearing information corresponding With the sub-index character on the first-named leaf and not corresponding index leaf Will occupy a central positionl in relation With the remaining leaves.

4. In a directory, the combination of a series of leaves, the uppermost leaf having different marginal index characters and being provided in alinement with at least one of said index characters With an index term of a subject of information and having` adjacent said term a sub-index character, and one of the other leaves bearing information corresponding with the sub-index character and having its tab alined with the index character With which the sub-index character is alined.
